what the heck is *THIS*???

Been trying to save a brain coral I posted about a while back that's been receding and is on it's last legs as of now. Tried a FW dip, an H2O2 dip, and just today bought some tincture of iodine from the pharmacy and used a few drops and dipped in that. When I removed the coral, these were squiggling around. Is it possible this is the root cause? If so, what are they and how do I kill them without bombing the rest of the coral?

I wish I could see the video.......not working on my browser

Brain coral need a lot of nutrition......not sure what the squiggly things are but don't sound good!

I am not actually sure if he said that, but dipping coral back to back in 3 various solutions is not without side effects for poor coral. Corals do not osmoregulate well and they stenohaline, meaning able to tolerate narrow range of salinity. Hydrogen peroxide dip is primarily to kill algae, but surely it will effect other organisms too. Tincture of iodine is antibacterial, but it is very concentrated so overall poor coral needs to rest a bit. Cannot comment on squiggly things as video didn’t load for me.
Overall all methods you used are legit, but it just might’ve been to much for your specimen.

They are worms, but I am no good with worms. Will post a snip of the video, so hopefully someone can ID.

Unlikely to be the cause. Probably just some detritus eating worms feeding on dead tissue.
You mentioned basic parameters in your other thread but never mentioned anything about nutrients, lighting, or flow. How long have you had the coral? Looks like a Trachy? Had it been healthy and growing for a long time prior to this problem? Is it relatively new? They are difficult to ship if they are on the larger size without the flesh around the edges getting damaged by the skeleton. How about a current picture? It's not very puffed up on the picture in the other thread which tells me there is something going on with it and it's not super happy.

Straight FW dip on a coral? That's harsh and usually never a good plan. Most I ever do is half SW/half peroxide and that is for killing algae on skeletons and plugs only. Dip for a minute maybe two at most. Dips for pests .. coralRX or the Bayer insecticide. Dip for 15min or so.. Dips for disease Cipro, Chemiclean. Dip for an hour a day with a couple dips a day or two apart. I have used short Iodine dips in the past but never had good results.

It looks like there is some sand on the skeleton in the photo on the other thread? Is the sand getting blown around where it is? They don't like a lot of flow, especially if it hits it sideways from the same direction for a long period.

The dips were not in the same day, but were applied over the past three weeks.
